APPARATUS FOR WEIGHING WOOL.

SPECIFICATION forming part of Letters Patent No. 247,334, dated September 20, 1881.

Application filed February 21, 1881. (ModeL) To all whom it may concern Be it known that I, J OHN F. GEBHART, of New Albany, in the county of Floyd, and in the State of Indiana, have invented certain new and useful Improvements in Apparatus for Automatically Weighing Wool for Carding-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My present invention relates to apparatus for weighing wool employed in that class of machines for feeding carding-engines which will be found in Patent No. 216,373.

Heretofore in these machines the scoop into which the wool falls from the wiper or stripping-apron, in order to be weighed, has been rigidly secured to the ends of swinging levers, and hence, if the wool falls into the scoop on the side that is next to the machine, it will require more wool to draw down the scales than it will when the wool falls into the scoop on the other side.

The object of my invention is to arrange the scoop so that the same quantity of wool will weigh the same, irrespective of the side of the scoop into which the wool falls; andit has for its further object to prevent the scoop from swinging or rocking, and to keep it from sagging at either end, as will appear.

In the drawings, which show only so much of an apparatus for feeding carding-machines as is necessary to illustrate my invention, Figure l is an end elevation of the box orbin for the wool, with my improvement applied thereto. Fig. 2 is a vertical section of the same, taken transversely through the box and scoop; and Fig. 3 is a front elevation of a portion of Fig. 1.

The letter A indicates the box in which the wool is first placed, and from which it will in practice be lifted by a toothed apron, and then carried to the scoop of the scales by awiper or stripping-apron, (not herein shown,l as will be found in the patent before referred to.

The letter B indicates the scoop of the scales, which consists of a long trough designed to be suspended in position to receive the wool from the stripping-apron and to discharge the same after a quantity of a given weight has been collected therein. This scoop is pivoted to the ends of the levers G U, which are fulcrumed about midway of their length upon arms D D, secured to the frame of the machine, the said arms having notches in their upper ends to receive the fulcrum-pins of the levers. The extent of vibration of these levers is determined by stops E at the sides thereof, and upon the rear ends of the levers are arranged adjustable counterbalance-weights F. By this arrangement the same quantity of wool will weigh the same, whether it fall into the scoop at the side nearest to or farthest from the machine. To the lower portion of the ends of the scoop are pivoted the short bars or fingers F, and the inner ends of these fingers are hung upon a horizontal bar, G, (see dotted lines, Fig. 3,) which extends across the breast or front of the machine. The ends of this horizontal bar are supported in bearings H, which are connected with the frame of the machine. By this means the scoop will be kept from rocking, and also it will be provided with additional end supports, which will obviate any lowering or sagging of the scoop at one end in case of an unequal distribution of the wool therein.

The scoop B may have its sides arranged to drop or open when properly filled, as is usual in this class of machines; but as this forms no part of my present invention further description of the method of operating the scoop is deemed unnecessary.

It will be perceived that by reason of the peculiar devices for supporting the scoop the said scoop will have a rectilinear vertical movement, and will not tip or swing toward the sides or ends. Consequently the leverage of the wool, in whatever position it may fall in the scoop, will always be the same, insurin g uniform weighing of the wool.

What I claim, and desire to secure by Letters Patent, is-

In a wool-weighing device for carding-machines, the transverse pivoted bar G and links F F for giving approximatelyparallel motion, in combination with the receptacle B, pivoted to the scale-beams U G, the box A, and the fulcrum-supports D D, all constructedand arranged substantially as set forth.

In testimony that I claim the foregoing I ICO have hereunto set my hand this 24th day of January, 1881.

J. F. GEBHART.
